Operations. During the 1960s, the Aerospace Medical Division managed laboratories, a hospital, a clinic, and a school, conducting aerospace medical research, providing medical care to USAF personnel, and leading medical education programs. It conducted medical testing, not only for USAF personnel, but also for NASA astronauts in the Mercury program. In the 1970s, the division's mission responsibilities expanded to include occupational and environmental health oversight for the USAF. During the 1980s, the division's mission evolved beyond aeromedical research, to include development of biotechnology systems, and it relinquished its hospital and clinic responsibilities. During the Gulf War, the Human Systems Division provided technological support for U.S. troops in Southwest Asia, such as chemical warfare equipment. In the 1990s, as the Human Systems Center, it integrated and maintained people in USAF systems and operations, serving as the service's agent for human-centered research, development, acquisition, and specialized operational support. The 311 Human Systems Wing focused on aerospace medicine, environmental safety, and occupational health programs for the Air Force.
